我正在尝试使用Openshift / Kubernetes来模仿volumes_from。我有容器A包装应用程序和容器B服务器打包的应用程序。
我不能使用init containers，因为我被卡在kubernetes 1.2上。
我已经尝试了postStart生命周期钩子，详情如下：
How to mimic '--volumes-from' in Kubernetes
但是，Openshift / Kubernetes总是抱怨容器A严重崩溃，因为一旦完成包装，它就会退出。
如何让Openshift / Kubernetes停止抱怨容器A崩溃，并接受它已完成它的工作？
或者是否有另一种方法让一个容器构建一个包以供另一个容器运行？
提前感谢您的时间。

我没有kubectl，而是使用oc describe pod myapp-2-prehook：
